It is difficult to give a rigorous definition of a separated flow, but it is relatively easy to learn how to distinguishing it from an attached flow. Just look at the 15 videos. Notice the main features of separated flows:

1. Fluid particles leave the vicinity of the surface at the separation point.

2. In the eddy the velocity is small.

3. In the eddy the fluid moves backwards.

Video 1. Separated flow past an aerofoil. Notice the flow reversal in the eddy, small value of the velocity in the eddy, and how the fluid particles leave the vicinity of the surface at the separation point.

Welcome to Flow Illustrator

This is an easy to use online tool to simulate fluid flow around objects. If you would like to make a video of the fluid flow around an object take a look at our guide on creating your image. Once you are ready you can make your video on this page. If you would like to know more about the parameters used on the page they can be found here.
